Lex V2: I am creating a test network of bots. I'm using two bots each having one intent. The build is successful but when I'm trying to test it I get the error There was an error getting the sentiment for this request. Try your request again. for any input. I have tested both bots separately and they both work properly on the alias and associated versions. I'm not even sure where to look into.
PS: both bots are hooked to a fulfillment Lambda function and the lambda function does not get invoked.
The problem was the IAM role. The IAM role should include AmazonLexV2BotPolicy and comprehend:DetectSentiment
